(And over time, CPU Prices drop as intel releases faster/later models.)Reader Reports: (later reports first.) If you've upgraded a Mini's CPU, send details (news at xlr8yourmac.com).( Note/Tip on OS X 10.7 Upgrades: For owners that swapped in a Core 2 Duo CPU, the original tip for Lion dev previews is reported to still work - I.E. A socketed CPU is a huge plus, although at some point future CPUs will not be compatible (and may use a different socket), but in the meantime it's a nice change to be able to use standard (high volume/commonly available) Intel CPUs for upgrades. The early Intel-based iMacs also had a socketed CPU and there are a couple C2D CPU upgrade reports here on those.)This page has pre-2009 model Mac Mini owner comments on Core 2 Duo (and some Core Duo) CPU upgrades as the (2006-2008 mfg) Intel-CPU Mac Mini has a CPU socket on the logic board (as did early Intel-based iMacs).Some reports include notes on updating mac mini 1,1 efi firmware/bootrom to mini 2,1 version for 3GB RAM support vs 2GB w/mini 1,1 - Guide to Flashing Mini 1,1 to 2,1 at ) There were several news page posts earlier in 2006 on Core Duo CPU swaps (before the Core 2 Duo), although they are not listed here, except for the one that included a step-by-step guide on Mini CPU swaps from May 2006 (2006 Mac Mini Intel CPU Upgrade Guide at and a later posted ifixit guide). (CPUs in 2009 and later Mac Mini models are soldered to the motherboard.) Sponsor OWC has Mac mini upgrades (ram, drives, etc.) and take-apart guide videos for 2006-2008 Minis and later models.It's been 6 months and operated flawlessly.I would recommend that people get all the parts together before opening up the Mini. Report has notes on ML/OS X 10.8.3)2006 Mac Mini T7200 Core2Duo CPU/HD/Optical Drive Upgrades:I upgraded the CPU, RAM, HDD and the optical drive in a 2006 Mac Mini ( originally 1.66GHz Core Solo) I bought to be used with a TV as a multimedia and web browsing machine. TIA!( Several reports below have notes on OS X Lion with C2D updated 2006-08 Minis. If there's an easier way (installer check edit, etc) send a note. The Lion volume should then work with the Core2Duo updated Mini (or iMac).I had the external drive partitioned into 3 partitions.Partition 1 was used to install 10.7 and reboot the MacBook. 26th post below) I finally was able to borrow an OS X 10.7 supported MacBook and installed 10.7 on an external hard drive. Good luck to all those who want to get the best out of their machines.(Follow-Up) OS X Lion Install on Core 2 Duo Upgraded 2006 Mini:(from mail - follow-up to previous C2D upgrade report)I recently sent a report on upgrading the processors on two 2006 mac minis with hopes of installing 10.7 at a later date. I like my Mini so much I have bought a second one! This one is a 2007 and will also be upgraded - T7600 2.33 Ghz processor, 4GB of RAM ( mini 2,1 EFI supports up to 3GB usable) and a bigger hard drive.Many thanks for your site, I found it helpful. If you plan on cloning your old hard drive onto the new one (as I did) then I recommend getting a firewire compatible caddy, as Snow Leopard doesn't always work with USB caddys when you try and format them for some reason - this problem held me up.All in all, a very worthwhile exercise. I upgraded to a T7200 2.0Ghz, 2GB of RAM, a SuperDrive from a '09 iMac (it can burn DL DVDs and cost $10 NOS) and a 1TB hard drive.
![]() What Is The Most Recent Os For A 2010 Mini Mac Mini 1This partition was then used to create a disk image that would then be cloned onto the mini's hard drive without the platformsupport.plist or any user accounts.When it came time to install (copy) 10.7.4 to my upgraded 2.16 Ghz Core mini, I created a new partition to clone the 10.7.4 disk image onto. This was mainly for backup purposes in case I messed something up and could not get 10.7.4 or 10.7.5 working on the mini.Partition 3 was used to install 10.7 and then apply combo update 10.7.4. I did not install 10.7.5 as I had read that some mac mini systems did not like this update so I felt I would ignore it for now.Partition 2 was used to create another install of 10.7 which was then used to create a disk image for cloning onto my mini without the platformsupport.plist. Only complaint so far is the lack of scroll arrows in Lion.I also found a non working 2006 1.5Ghz Core Solo that needed some TLC and would not power up. I am happy to say my mini booted up just fine and 10.7.5 is working well so far. This updated restored the platformsupport.plist, but I was able to remove it before restarting the mini. It booted up and I was greeted with the account setup screen.Since this worked, I went ahead and installed the 10.7.5 combo update. After the image was restored to the new partition, I rebooted my mini holding down the option key to selected the new Lion partition. Got what I was hoping for, a startup chime and the display showed a folder with a question mark in it.I then used the external drive to boot the mini with 10.7.5, formatted the internal hard drive and cloned 10.7.4 onto the internal drive and rebooted. Got everything put back together and pressed the power button. I had a broken macbook with 2GB of memory laying around and installed it in this mini. The pins released easily (Unlike my 1.66 Core Duo). Replacing the CPU was fairly quick as this was my third time doing this type of upgrade. Since I had an extra 1.83ghz Core 2 Duo CPU laying around I decided to upgrade the CPU. This mini was already upgraded to 2.0GB of RAM. Had a fun time doing the upgrade.Today I upgraded my Mac Mini Early 2006 1.66GHz Core Duo to a used 2.16GHz Core 2 Duo T7400. Was able to remove the pins easily and reuse them. The hardrive in the mini crashed and I figured it would be a good time to install the T5600 in it. I plan to install 10.7 on the 2.16GHz machine just to see if I can get it to work. Took 10 minutes to get one pin out as one side kept expanding when I tried to push the pin through the CPU hole.Both Mac Mini Systems are running Mac OS 10.6.8. Well, my Mini let me know. My wife's Mini made me wonder why people were having problems getting the pins out. (They're probably not designed to be used multiple times anyway.) As plastic screws are very hard to find here, I used 25-mm-long M3 metal screws instead. As to Lion, it's hard to find a second Mac here to upgrade to it.On dismantlement of the CPU heat sink, I broke one of the plastic pins. Alas, the Mobile Intel 945 Express chipset limit of 4 GB leads to only 3 GB usable by the operating system. Temperatures are close to what they were before the upgrade, the T7400 runs about 10☌ cooler than the older T2300 when idle or browsing.2006 Mini Core 2 Duo (T7600/2.33GHz) CPU Swap, Mini 2,1 EFI Update: (with source for heatsink retaining pins) (from mail)Thank you for the possibility to share experience on Mac mini upgrades! The comments on your website ( this page) and the article at ifixit ( Replacing mini Model A1176 Core 2 Duo Processor) are very helpful and I was able to upgrade my Model 1176 CPU to T7600 ( 2.33GHz), firmware to 2,1 and RAM to 4 GB ( 3GB usable w/2,1 rom vs 2GB w/1,1 rom) without big problems. When running BONIC the CPU cores go up to 86☌. I found a couple programs that do not run if the mini was still showing Macmini 1,1.Temperatures run about 66☌ when the systems are just being used to browse the net and watch Netflix. Filmora video editor for mac serialHardware Stores usually have them, as well as nylon screws.-M.)Turning the nuts on the top side of the heat sink, I adjusted the length (and hence the tension) of the springs to be about the same as if the original pins were used.
